I'm so sorry that the man you gave so much to, who you invested in, who you thought was worthy of your time and your effort and your love, has turned out to be so unworthy and ungrateful.
I'm so sorry that he saw you more as a housing provider than a partner.
I'm so sorry that he disrespected you so much that he that he could not be bothered to teach his children how to behave considerately in your home.
And I'm so sorry that he disrespected his own children so much that he could not be bothered to teach them how to behave considerately, even in what they must have considered their home half the time.
I'm so sorry that his own lack of self respect, perspective and self-reflection meant he never thought you were worthy of his consideration.
He was never worthy of your time, energy or love. And I'm so sorry that he deceived you into thinking he was.
You deserve someone worthy. Because you are worthy.
